Physiology, Frank Starling Law - StatPearls - NCBI Bookshelf. The Frank-Starling relationship is based on the link between the initial length of myocardial fibers and the force generated by contraction. There is a predictable relationship between the length between sarcomeres and the tension of the muscle fibers Frank-Starling Law. The Frank-Starling law describes the relationship between the force of contraction and the initial length of muscle cells. The sarcomere length associated with the most powerful contraction is 2.2 μm because there is maximal overlap of myofilaments in this configuration Physiology, Frank Starling Law The Frank-Starling relationship is based on the link between the initial length of myocardial fibers and the force generated by contraction. There is a predictable relationship between the length between sarcomeres and the tension of the muscle fibers. There is an optimal length between sarcomeres a

The Frank- Starling law states that the force or tension developed in a muscle fiber depends on the extent to which the fiber is stretched. In a clinical situation, when increased quantities of blood flow into the heart (increasing preload), the walls of the heart stretch the frank-starling law, also known as starling's law, or frank-starling law of the heart, is a physiological theory which states that, 'the strength of the heart's systolic contraction is directly proportional to its diastolic expansion, with the result that under normal physiological conditions the heart pumps out of the right atrium all the The Frank-Starling Law is the description of cardiac hemodynamics as it relates to myocyte stretch and contractility. The Frank-Starling Law states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch causing a more forceful systolic contraction

Frank Starling Law states that the stroke volume and cardiac output occur in response to an increase in venous return or end diastolic volume. It is based on length-tension relationship in the ventricle.

The law states that the stroke volume of the heart increases in response to an increase in the volume of blood in the. The Frank-Starling law is all about optimal actin-myosin coupling - at the right amount of stretch, there's maximal coupling of myosin heads to actin and hence the force generated is maximum. This is not a law of physics - it is a biological property of muscle fibers

The Frank-Starling law of the heart is one of the most important intrinsic properties of cardiac muscle. It states that a change in venous return (preload) confers a change in the force of cardiac contraction (stroke volume or cardiac output) through increased sarcomere lengthening and excitation-contraction coupling of the muscle fibers Frank-Starling law (frănk′stăr′lĭng) In cardiac physiology, the rule stating that cardiac output increases in proportion to the diastolic stretch of heart muscle fibers. Medical Dictionary, © 2009 Farlex and Partners Want to thank TFD for its existence 法蘭克-史達林機制(英語: Frank-Starling mechanisms ),是心臟的一種代償機制。指的是心臟的每搏輸出量在所有其他因素保持不變的情況下,會隨著心臟前負荷(心肌在收縮前所承受的負荷)的增加而增加。在一定的限度內,增加心臟的前負荷,回心血量增多,心臟內血液總體積充盈(舒張末期結束後的容積增加),從而導致心臟輸出量增加 the Frank-Starling law of the heart as the principal mechanism by which the heart adapts to changing inflow of blood. When the cardiac muscle becomes stretched an extra amount, as it does when extra amounts of blood enter the heart chambers, the stretched muscle contracts with a greatly increased force, thereby automatically pumping the extra.

The Frank-Starling law of the heart indicates that the increased filling pressure of the right heart results in increased cardiac output. Any increase in output of the right heart is quickly communicated to the left heart as an increased filling pressure The Frank-Starling law of the heart (also known as Starling's law or the Frank-Starling mechanism) states that the more the ventricle is filled with blood during diastole ( end-diastolic volume ), the greater the volume of ejected blood will be during the resulting systolic contraction ( stroke volume ) The Frank-Starling Law describes the relationship between LVEDV and CO. According to the Starling Law, CO increases with increasing left ventricular preload until the left ventricle reaches excessive end-diastolic volumes. With excessive end-diastolic volumes, the CO does not change and may actually decrease The Frank-Starling mechanism plays a role in the compensation of systolic heart failure, buffering the fall in cardiac output to help preserve sufficient blood pressure to perfuse the vital organs. Heart failure caused by the impaired contractile function of the left ventricle causes a downward shift of the left ventricular performance curve
